lMPROVEMENT IN SOFA-BEDSTE ADS.

Specification forming part of Letters Patent No. 7,404; dated May 28, 1850.

To all whom it may concern:

Be it known that I, A. G. WARREN, of Norwich, in the county of New London and State of Connecticut, have invented certain Improvements in Sofa-Beds and I do hereby declare that the following is a full, clear, and exact description'of the principle or character which distinguishes them from all other things before known, and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which- Figure 1 is aview as a sofa; Fig. 2, aperspectiveview arranged as a bed; Fig. 3, a cross-section; Figs. 4 and 5, sections showing different devices for moving the head and foot boards; Fig. 6, the back, showing the springbolts.

The combination of a sofa and bed in the same article of furniture has been brought into considerable use, and would have been much more generally introduced but for the inconvenience of changing the form from one tothe other, being in some instances almost equal to thetronble of setting up a bedstead every night and taking it to pieces in the morning, and in those in which the back is is made to let down an uncomfortable gap or hard place is to be felt in the center of the bed where the cushions meet, which deprives its unfortunate occupant of rest. In my improvement the change is instantaneously made from a sofa to a bed, and vice verse. I make the back with springs of equal elasticity with those of the seat, so that when used as a bed they form a broad and even surface. The joint between the spring-cushions is so even and equally elastic with the other parts that it-cannot be feltby the recumbent. There is also a drawer,which serves the double purpose a. The'cushions are constructed with spiral" springs c, which are confined to a proper position by the cords f in the usual manner, except where the two cushions meet, where the cord, instead of being passed across the upper end of the springs, is only fastened to one edge, and then passes diagonally to near the middle of the spring, where it is again fastened, and from thence to the frame of the cushion. This leaves the outer edge of the spring free and makes a square corner to the cushion.

To support the back a when down, there is a drawer, g, which runs out on the casters h, on which the back rests.

Within the arms or ends of the sofa i are the sliding head and foot boards j,which are made to slide out when the back a is lowered. I have several plans for effecting this object, one of which is shown in Fig. 4, where k is a. segment-rack attached to the backa. The teeth of the segment it work in the pinion l, which turns in bearings between the arm and seat of the sofa, having another pinion at tached to it, which works in the rack m on the bottom of the sliding head-board, causing it to draw out when the back a is lowered, and

to return'within the arm when the back is raised.

Another plan' is shown in Fig. 5, where n is an arm attached to the back at, having at its extremity a pin, 0, which works in a groove, 19, in the head-board, causing it to be moved in or out, as before.

The arm may be omitted and the pin placed in the back at q, which would then. run in the groove, (dotted at r,) having the same effect, but causing the groove to be exposed to view, which is not the case on the other plan.

The back a is fixed in an upright position by spring-bolts s, which shoot into holes in the arms a and are drawn back by turning the handle t, acting on the lovers to, and the wires connecting them with the bolts 6, as shown in Figs. 3 and 6. In the armsiare the pins 'v,which fit in corresponding holes, in the back a, giving increased firmness tothe structure.

Having thusv fully described my,improve= ments in sofa-beds,what I claim as new therein, and desire to secure by Letters Patent, isas the back is raised or lowered by the con- 1. The drawer with casters, made so as to trivances as above described, or other equivaserve the' double purpose of a receptacle for lent devices.
